Definitions
- the invention relates to a screw terminal for connection electrical conductor with a clamp as a pressure piece, one Screw and a clamp body, the screw in Clamping bracket is clamped and via a thread in the clamping body taking the clamp in relation to the clamp body is adjustable.
- a generic screw terminal in the version according to 3 is known. This is where the clamping force is applied a screw with special geometry used to the Connect the screw captively to the clamp. The most lower end tapered screw is over a Bore held in the leg of the clamp bracket.
- the invention has for its object a screw terminal for connecting electrical conductors of the type mentioned above with regard to construction and manufacture as well as assembly and disassembly to simplify and design inexpensively.
- the object is achieved in that the screw is standardized Grub screw is executed in the flattened part of a roof-shaped first leg of the pressure piece lies on.
- An advantageous embodiment is when the screw in a cylindrical recess of a second leg of the Pressure piece is held.
- FIG. 1 shows a screw terminal 1 according to the invention a clamp 2 as a pressure piece, a screw 3 and one Clamping body 4 is composed.
- the screw 3 is as conventional grub screw according to the DIN 915 standard. It is clamped in the clamping bracket 2, being one hand in the flattened area of a roof-shaped first leg 5 of the pressure piece 2 and on the other hand in one cylindrical depression 6 of a second leg 7 of the pressure piece 2 supports.
- the first leg 5 is solid, i.e. executed without breakthrough, which means greater resilience when connecting electrical conductors.
- FIG. 2 shows the screw terminal 1 in a sectional view in particular the flattened area 8 of the roof-shaped first leg 5 of the pressure piece 2 can be seen.
- the choice of dimensions ensures that at each tolerance position of the components of the clamping bracket 2 does not have the screw 3 slips and thus the screw drive, e.g. via the hexagon socket or the slot in the screw covered.
- the screw 3 is in the before the assembly of the pressure piece 2 Clamping body 4 screwed in. Then the clamp body 4 connected with the screw 3. The dimensions of the clamp 2 are chosen so that it is without plastic deformation at the top End of screw 3 hooked and turned over the lower end can be.
